Description

Shoe last and supporting seat mounting structure

Technical Field

The utility model relates to a shoe tree and supporting seat mounting structure.

Background

The shoe tree is used as the shoe forming mold to determine the shoe shape and style, and to determine whether the shoe is fit or not, and to protect the foot. The existing shoe tree is usually connected and matched with a supporting seat, and in the shoe making link, the supporting seat and shoe making equipment are required to be connected and matched, so that the functions of transferring, positioning, removing the shoe tree, connecting the shoe upper, injecting and the like of the shoe tree are realized.

The Chinese patent of the applicant's japanese patent application discloses a last assembly (CN 115024560 a) comprising a last and a support base fixed to the last, wherein the last comprises a sole portion and a heel portion, the sole portion and the heel portion form a sliding connection fit, the support base comprises a first support base fixed to the lower end of the sole portion and a second support base fixed to the lower end of the heel portion, and a transverse insertion positioning fit is formed between the heel portion and the second support base. The sole portion and the heel portion adopt sliding connection matched connection mode, after shoemaking is accomplished, through operation sole portion and heel portion relative slip for the whole length of shoe tree obtains reducing, thereby can be convenient take off the shoe from the shoe tree. In addition, adopt horizontal grafting location cooperation mode between sole portion and the first supporting seat of shoe tree and between heel portion and the second supporting seat of shoe tree, restrict through first spacing component, second spacing component after grafting, prevent to peg graft the separation each other between the two parts of location cooperation transversely. And positioning concave holes for being matched and positioned with the clamp of the mechanical arm are also formed in two sides of the first supporting seat. The inner hole of the second limiting member can be matched with a bolt on a fixture clamp of the shoemaking workbench for positioning.

In the above-mentioned patent, connection structure between supporting seat and the shoe tree is comparatively complicated, and the connection characteristic is more, and the assembly process is also comparatively loaded down with trivial details, and supporting seat and shoe tree are difficult to dismantle the change after the assembly is accomplished. Because the supporting seat is often required to be matched with a clamp, a mechanical arm, a tray and the like of a shoemaking production line for positioning, abrasion is easy to occur after long-term use, and shoemaking precision is easy to be reduced. Often, the entire last and mounting structure of the support base need to be replaced after long-term use, which results in an increase in the cost of manufacturing the shoe. At the same time, the support base is generally made of a harder and wear-resistant material, such as steel, for example, due to its service life, which also results in increased costs of the last and the mounting structure of the support base, and also results in a greater weight of the last assembly as a whole, which is detrimental to transfer, transport, etc. of the last assembly.
